Tensorflow is only compatible for 64 bit version of Python. So, make sure it is by :
>python
Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 22:22:05) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
Then, simply, upgrade pip using:
python -m pip install --upgrade pip
Lastly, install tensorflow:
pip install tensorflow
Done!
You can verify the install using:
python3 -c "import tensorflow as tf; print(tf.reduce_sum(tf.random.normal([1000, 1000])))"
